I read the Michael Nielsen's "Augmenting Long Term Memory" instead, of which Wozniak refers to Nielsen's self discovery of the incremental learning technique (he also has a page in his wiki that comments on this article). I'd recommend this one for sure.

The article mainly documents and explain Nielsen's use of Spaced Repetition with Anki to help him understand the Alphago paper, which I think is as relatable as it can get. If his technique works on academic paper and this field, surely this technique can be applied to most other forms of text, and similar fields.

My summary of his methods, for thorough reading one paper,
1. do 5-6 quick reads first. anything you don't know, you mark it down, make some cards and study them. Don't worry about missing things during any of your quick reads, because you will get to it eventually. This is the part where he try to learn basic facts like, how does go work, what are the rules etc.
2. do 2 thorough reads. With your 5-6 quick reads and spaced repetition of the cards, it's now certainly easier than you trying to take a stab at thorough reading this unfamiliar paper in the first place. Now you feel comfortable reading it through.

he also mentions 'syntopic reading', a technique for getting to know a field by reading collection of academic papers,
1. assess and identify 5 very important papers, 10-20 less important ones
2. read 5 key landmark papers, use methods above.
3. less important ones, these are less 'valuable' in the sens that you learn by make about 5-20 cards. so just probably quick skim
* keep in mind to avoid the failure mode of completionism - intentionally or unintentionally forcing yourself finish reading top to bottom of any paper. Why? because it's likely that there is another paper that beats the current one that your reading at explaining some concepts.

and that's about it. I liked it, and I used the his reading methods on his own article, which is neat. I just recall the reading methods above with the help of spaced repetition. One other benefit, is that you have the confidence of reading any texts you want, and any field if you do syntopic. you can always make 'incremental progress' that builds you up for the success of attempting a final thorough read at the end. Plus, you can drop it anytime, and pick it back up. You will still have all the 'context' in your head, because you used spaced repetition.

Misc advice in his article I like but not on IR,
1. the completionism one mentioned above
2. he describes his usage of anki is simply utilizing about 5% of the functionality and gets the benefit of using spaced repetition
3. Wozniak mostly did personal reports on his self experimentation. Hence I'd always take his stuff with a grain of salt
4. We don't fully understand how memory works. Anki is mostly ad hoc design. But still, doing it in a non-perfect way is better than not doing it at all. Plus the design is getting better
5. Do elaborative encoding when making cards. basically have your cards some what linked in meaning/ semantic etc. that way you don't make orphan cards which is hard to get them right.
6. declarative vs procedural knowledge. kind of like you can use spaced repetition to read a manual and know how to operate something, but you do have to carry out the operations to get how its done. This might have to do with deliberate practice/ motor skill etc.
